Deposit preform injection moulding device with additional magnetic filed

Abstract

The invention belongs to the field of metal blank processing, and particularly relates to a deposit preform injection moulding device. The deposit preform injection moulding device with an additional magnetic filed comprises a crucible (1), an atomizer (2), a charging electrode and a depositor (4); the crucible (1) and the atomizer (2) are communicated by a guide pipe; the depositor (4) is arranged below the outlet of the nozzle of the atomizer (2); an atomized grain flying region (5) is arranged between the nozzle of the atomizer (2) and the depositor (4); the charging electrode (3) is arranged at crushing sites where molten metal (6) is separated into the atomized grains (8); and a magnetic field generation device (9) is arranged around the atomized grain flying region (5) and under thecharging electrode. In the invention, the flying paths of the atomized grains can be changed to reduce the taper divergence angle of the atomized grain flying region by using an additional magnetic filed, thereby greatly improving the yield of the molten metal; and in addition, by changing the direction and magnitude of the magnetic filed, the moulding quality of deposit preform can be improved and the production cost of the deposit preform can be reduced, therefore, the economic benefits can be improved.

Description

technical field [0001] The invention belongs to the field of metal billet processing, in particular to a deposition billet spray forming device. Background technique [0002] Spray forming is an advanced material preparation technology developed on the basis of rapid solidification powder metallurgy technology. The outstanding advantage of the spray forming technology is that it combines the atomization and deposition forming of the metal melt into one, and can directly produce the final ingot with large size and rapid solidification characteristics from the liquid metal, which overcomes the various powder metallurgy technology processes, The serious problem of oxidation enables spray-deposited materials to have higher comprehensive mechanical properties than powder metallurgy materials. figure 1 A schematic diagram of the principle of spray forming is given. It uses the high-pressure inert gas 7 in the atomizer 2 to atomize the high-temperature molten steel 6 flowing out o...
